M/l EA/ 70/? 1 JAMiS 6. PIE/PR Y BY @WZMA @M ATTORNEY United StatesPatent 3,206,804 ADJUSTABLE MOUNTING FOR SASH SLIDE RAIL James G. Perry,12981 Capital Ave., flak Park 37, Mich. FiledJuly 28, 1964, Ser. No.385,704 2 Claims. (Cl. 20-522) This invention relates to the buildingindustry and has particular reference to removable sash windows.

An object of the invention is to provide an adjustable mounting for theslide rail of a removable sash window, such as disclosed in myco-pending application No. 245,708, filed December 19, 1962.

Another object of the invention is to provide an adjustable mounting forthe slide rail of a removable window, which is constructed and arranged,so that the slide rail may be stored and shipped in flat condition andwithout the mounting screws protruding from the slide rail during thestorage and shipment ,of the device.

Another object of the invention is to provide an adjustable mountingmeans for a compound weather strip, or slide rail, for a removable sashwindow. In this disclosure a compound weather strip, or slide rail, willbe understood to be a unitary weather strip, or slide rail, which servesboth the upper and lower sash of a double hung window.

Another object of the invention is the provision of an adjustablemounting for the slide rail of a removable Sash window, which may bequickly and efiiciently mounted to the side jamb ,of the window frame byusing the openings provided in slide rail and retainer for guides indrilling holes in the side jamb for the subsequent introduction of thescrews which are to mount the slide rail to the jamb. This is animportant feature of the invention as it enables the installer toperfectly align the slide rail when it is installed. This result is notpossible with devices now known to the public because the mountingscrews are permanently fixed to the slide rail at the factory and alwaysprotrude beyond the rail. The protrusion of all of the screws beyond theback face of the slide rail before and during installation provides apoor support and causes a wobbling and unsteady movement of that portionof the slide rail, which is removed from the mounting screws initiallyworked on during the attachment of the slide rail to the side jamb ofthe window frame. Under such conditions it is impossible to properlyalign the slide rail. Unless there is a perfect alignment of the fulllength of the slide rail during its installation, there always will bedifficulty in sliding the window sash and removing the same from theadjustable slide rails.

This invention may be considered an improvement on the inventiondisclosed in Patent No. 3,103,711, issued to Teggelaar. In the referencepatent the mounting screws are permanently staked to the supportmembers, or retainers, which hold the springs in position, consequentlythe mounting screws always protrude from the slide rail during thestorage and shipment of the slide rails, and remain so until the screwsare permanently set into the side jambs of the window frame. Asindicated above, the permanent protrusion of the mounting screws makesit very diflicult to properly align the slide rails during theirinstallation.

The instant invention has a further advantage over the device disclosedin the reference patent, in that it allows greater adjustment betweenthe support members, or retaining members, and the slide rail. In thereference patent, because the attaching screws are staked to the supportmember, or retainer, the adjustment between the support member, orretainer, and the rail is limited to the distance between the ends ofthe support member, or retainer, and the body of the slide rail. In theinstant invention, however, because the adjustment screw is not stakedto the retainer, or support member, but enters the openings in the railand support member freely and is later fixed to an independent washer,which abuts the small end of the spring, the spring may further beplaced under greater compression, by rotating the screw, even after theends of the support member, or retainer, have contacted the body of theslide rail. Because of the ability to further compress the spring ashereinabove described, greater adjustment may be made on the slide railthan is possible with the structure disclosed in 'the reference patent.The additional adjustment which is made possible with the instantinvention is quite important when it is necessary to compensate for awindow sash which may have been milled undersize as to overall width.

It is therefore an object of this invention to obviate the foregoingdifliculties and to provide .an adjustment for a slide rail which hasmany advantages over devices of that character now known to the public.V I

The foregoing and other objects and advantages of the invention willbecome more apparent as the disclosure proceeds, reference being madefrom time to time to the accompanying drawing, forming a part of thewithin disclosure, in which drawing:

FIG. 1 is a transverse section taken through a compound weather strip orslide rail embodying the invention. This view shows the weather strip,or slide rail, without the attaching screws, and shows the condition ofthe device when it is in storage, or intransit, prior to itsinstallation on a window frame.

FIG. 2 is a transverse section taken through a window frame to which thedevice shown in FIG. 1 is to be mounted. This shows the double hungwindow frame before the window sashes are installed in the frame, andshows the mounting screw as it is about to be entered in the bore(broken lines) previously drilled in the side jamb of the frame, usingthe openings in the weather strip, and the retainer as guides. In thisposition no compression has yet been put on the spring by the screw.

FIG. 3 is a section similar to FIG. 2, but illustrating the window frameafter the upper and lower sashes have been installed in the frame, andafter the mounting screw has been inserted in the side jamb of thewindow frame, and drawn up so that the retainer is inoperative and thespring is under compression between the washer and the back of theweather strip.

Referring now more particularly to the drawing, it will be understoodthat in the embodiment herein described the reference character 7indicates, in general, the body of a weather strip, or slide rail, for adouble sash window frame.

In this embodiment the member 7 is preferably made of a rigid extruded,plastic material, and is constructed and arranged so that it serves boththe upper sash and the lower sash of a window. The member 7 is ofsufficient length to extend the top to the bottom of a window opening,and as stated before, is adapted to Weatherstrip both the upper sash andthe lower sash and is resiliently mounted as hereinafter described, sothat. either sash may be removed from the frame by compressing theflexible mounting to provide clearance, whereby the sash may be removedas in conventional practice.

The member 7 is provided with two hollow rectangular portions 8 and 9,which engage channels 10 and 11 (FIG. 3), formed in the side members ofthe window sash. Each member 8 and 9 (FIG. 1) is provided with alongitudinal opening 12 to receive the balancing mechanism (not shown)of the window sash.

The wall 13 of the slide rail is provided with an opening 14 ofsufficient diameter to permit the passage therethrough of a mountingscrew 15, by which the slide rail 7 may be secured to the side jarnb 16of the window frame (FIGS. 2 and 3). The window frame is 33 alsoprovided with conventional back stop 17, front member 18, and trimmolding 19.

The opening 14 in the wall 13 has an inturned edge 20, which serves tohold against displacement one end of a compression spring 21, the otherend of which abuts a washer 22, which is carried in a U-shaped supportmember, or retainer 23. The outer ends of the retainer 23 are heldbehind shoulders 24, forming part of the weather strip, or slide rail 7.

The spring 21 is positioned between the wall 13, and the washer 22, andthe retainer 23, under a sufficient degree of compression to hold theparts in position during storage and transportation, as illustrated inFIG. 1.

The washer 22 and the retainer 23 are each provided with a bore 25, 25A,having a sufficient diameter to permit the shank of the screw 15 to passtherethrough. The bore 25A in the retainer is larger than the bore 25 ofthe washer. The washer 22 is of the lock-on type and is constructed sothat when the screw 15 is drawn down, so that the head of the screw 15contacts the washer 22, as shown in FIG. 3, the washer 22 will thenbecome locked on the shank of the screw, and will rotate with the screwand may be advanced or retracted as the screw is turned.

It will be understood that after the screw 15, and the washer 22, arelocked together, and the screw 15 is then backed out of the bore 26 adistance, increased compression is built up in the spring 21, as shownin FIG. 3. In this condition the retainer 23 becomes loosely mounted onthe shank of the screw 15 and serves no further purpose.

By the same token, the compression of the spring 21, now being betweenthe washer 22, and the wall 13 of the slide rail, it is obvious thatvarious degrees of compression can be exerted on the spring 21 by therotation of the screw 15.

This is an important feature of the invention as it enables theapplicant to get a greater amount of adjustment on the slide rail thanis possible with devices now known to the public. This arrangement alsopermits the combined openings in the wall 13, the washer 22, and theretainer 23 to be used as guides in drilling the bore 26, before themounting screw is inserted. With this arrangement the slide rail can beaccurately mounted on the side jamb 16 and on the job duringinstallation.

In FIG. 3 the reference character 27 indicates the upper sash, and thereference character 28 indicates the lower sash of a double hung window.Each sash 27 and 28 is provided with the conventional glass panel 29.

It is believed that the operation of the device is obvious from theforegoing description.
